KiCad Designer for School Access Control System
Budget: $10 – $30 USD
Hi,
I'm a student working on an access control system for our school's IT labs. We already have a working prototype and the firmware/software side handled — what I need is a properly designed PCB in KiCad to replace my breadboard version, since PCB design (especially RF and PoE) is outside my expertise.
Requirements:
PN532 RFID/NFC reader with antenna (on-board trace or module, your recommendation)
ESP32-S3 as main MCU
Standing/vertical form factor, board size 80mm x 35mm, 2-layer PCB, sized to mount inside a 3D-printed enclosure (mounting holes needed)
RJ-45 jack with PoE (802.3af preferred) for network + power — note ESP32-S3 has no built-in Ethernet MAC, so needs an external PHY (e.g. LAN8720) via RMII
Relay output for a 12V or 24V door lock, with proper flyback protection and isolation from the logic side
Multiple power inputs — 12V DC, 24V DC, or PoE — board should safely handle whichever is connected, with reverse-polarity/overvoltage protection
2x WS2812B RGB LEDs at the bottom of the board, for status indication
Deliverables: full KiCad project (schematic + PCB + BOM with sourceable parts), Gerbers for fab, and a pinout doc so I can adapt my existing firmware.
